Abû Ayyûb al-Ansârî relates that Allah's Messenger (peace be upon him) says: "Whoever fasts the month of Ramadan and then follows it with six days of fasting in the month of Shawwâl, it will be as if he had fasted the year through." [Sahîh Muslim (1163)]

The month of Shawwâl is singled out for the observance of extra fasts, since this month follows immediately after Ramadan. The six days of voluntary fasting are to the obligatory fast of Ramadan what the Sunnah prayers are to the obligatory prayers.

It is related from Thawbân that the Prophet (peace be upon him) said: "The fast of Ramadan is like observing ten months of fasting. Fasting six days of Shawwâl is like observing two months of fasting. This together is like fasting throughout the year." [Sahîh Ibn Khuzaymah (2115) and Sunan al-Nasâ'î al-Kubrâ (2860) – and authenticated by al-Albânî]

Al-Nawawî observes [Sharh Sahîh Muslim (8/56)]:

Scholars have explained that it is like observing a year of fasting because the reward of one's good deeds are multiplied tenfold. Therefore fasting the month of Ramadan is like fasting for ten months and fasting six days in the month of Shawwâl is like fasting for two months.Virtues of Fasting Six Days in Shawwâl

1. Fasting six days in Shawwâl after observing the Ramadan fast gives the person the reward of fasting throughout the year.

2. The fasts of Sha`bân and Shawwâl are like the Sunnah prayers that accompany the five obligatory prayers. Like the Sunnah prayers, these extra fasts cover up for the deficiencies in our performance of our obligatory worship. On the Day of Judgment, our voluntary acts of worship will compensate for the shortcomings in how we carried out our duties. Most of us have deficiencies in our observance of our Ramadan fasts and we need something to cover up for those deficiencies.

[Note: The deficiencies being discussed here are not missing days of fasting. Rather, they are the deficiencies in our conduct that detract from the value of our worship.]

3. Our return to the habit of fasting right after Ramadan is a sign that our Ramadan fasts were accepted. When Allah accepts our worship, He blesses us to engage in further acts of piety. The saying goes: The reward of virtue is further virtue. Therefore, following one good deed with others like it is a sign that the first deed had been accepted by Allah. By contrast, if a person's good deed is followed by a sinful one, it is an indication that the first good deed might not have been accepted.

4. Those who observe the fast of Ramadan are given their recompense of the day of`Id al-Fitr, the day when the fast is rewarded. Getting into the habit of fasting again soon thereafter is a means of giving thanks to Allah for the blessings that we have received. There is no blessing greater than forgiveness for one's sins, and we know that fast of Ramadan is recompensed with forgiveness of one's previous sins.

Indeed, Allah has commanded us to give thanks for the blessings of the Ramadan fast and to do so by making mention of Him and through other means of giving thanks. Allah says: "(He wants you) to complete the number of days, and to glorify Him in that He has guided you; and perchance you may give thanks." [Sûrah al-Baqarah: 185]

Fasting these days in Shawwâl is one way for us to express our thanks for Allah blessing us in our observance of the Ramadan fast.

It is known that some of the Pious Predecessors would try to get up at night to pray the Tahajjud prayer. When Allah blessed them to wake up and do so, they would fast the next day in thanks to Allah for blessing them to observe that prayer.

Once Wuhayb b. al-Ward was asked about the blessings of various acts of devotion and he replied: "Do not ask about the blessings that can be earned by performing these acts of worship. Rather, ask how you can show your thanks to Allah if He blesses you to perform them, for he is the one who assists us in doing so."

Every blessing that Allah gives us is something that we have to be thankful about. Moreover, when Allah blesses us to show thanks, this is a further blessing from Allah that deserves further thanks from us. If we show further thanks, this in turn is another blessing deserving our gratitude. There is no end to this and we can never be thankful enough. When we recognize that our thanks is never enough, this is the highest expression of gratitude we can give.

The Legal Ruling Regarding the Six Days of Shawwâl

Al-Shâfi`î, Ahmad b. Hanbal, and Ishâq al-Râhawayh hold that is preferable and recommended to fast six days in the month of Shawwâl. This opinion has also been related from Ibn `Abbâs, Ka`b al-Ahbâr, Tâwûs, al-Sha`bî, Maymûn b. Mahrân, and Ibn al-Mubârak.

They base their opinion upon the hadîth that we have discussed above.

Others have regarded fasting six days in the month of Shawwâl to be something disliked. This view has been related from Mâlik and Abû Hanîfah. They argue that it is feared from the general public that they might misconstrue fasting these six days to be something obligatory. They also see it as emulating the People of the Scripture to exceed the number of fasting days in the prescribed month of fasting.

However, these objections are spurious in the face of the clear statements of the Prophet (peace be upon him) that encourage this fast. If we were to abandon a Sunnah act on the grounds that we are exceeding what is obligatory, then we would have to abandon all recommended fasts, including the fast of `Ashûrâ' and the fast of the middle of the month.

It has been related that Mâlik used to personally fast six days in Shawwâl. Also, later Hanafî scholars decided that there is no objection to fasting these days.

The Mâlikî jurist Ibn `Abd al-Bar explains [al-Istidhkâr (3/380)]:Mâlik did not know of the hadîth related by Abû Ayyûb al-Ansârî, even though it is a hadîth from the people of Madînah. No one possesses all the knowledge held by others. Mâlik explained and clarified what he disliked about it – He was afraid that it would be added to the obligatory fast of Ramadan by the general public. Mâlik was extremely cautious when it came to matters of religion.

As for fasting six days in the month of Shawwâl to seek extra blessings – as Thawbân depicts it – this is something that Mâlik had no objection against – and Allah knows best – since fasting is a person's protective shield and its virtues are well-known. When we give up our food and drink for Allah's sake, it is a virtuous and good deed. Allah says: "and engage in good works that perchance you will be successful." [Sûrah al-Hajj: 77]

Mâlik was well aware of all this.

How We Should Fast the Six Days in Shawwâl

There are various opinions about this question:

1. Some scholars hold the view that it is preferable to fast the six days in consecutive order, starting from the second day of Shawwâl. This is the view of al-Shâfi`î and Ibn al-Mubârak.

2. Others are of the opinion that it is preferable to fast the six days intermittently, spreading them out throughout the month of Shawwâl. Thisis the position of Ahmad b. Hanbal and Wakî`.

3. Then there are those who hold the view that the days should all be postponed until later in the month and not close to the day of `Id, which is a time of celebration and feasting. They prefer fasting the three days in the middle of the month (ayyâm al-bîd) along with the three days right before or after. This is the opinion of Ma`mar and `Abd al-Razzâq.

There is considerable flexibility in all of this. We can choose to follow any of these approaches that we wish.
